ARE THERE ANY SPECIFIC MORPHOPATHOLOGICAL FEATURES IN EMERGENCY COLON CANCER SURGERY?
The increased incidence of colon cancer patients requiring emergency surgery should raise more interest in its complete morphopathological characterization. We performed a retrospective analysis of all colon cancer patients admitted through the emergency setting and operated in our Institution during the last 5 years. Special emphasis was put on the morphological features of the cases, such as histopathologic type, grading, TNM staging, tumoral inflammatory infiltrate, perineural and vascular invasion.We identified 104 patients that underwent radical colon cancer surgery in the emergency setting between 2017 and 2021. Most cases were located on the sigmoid colon and were diagnosed as either locally advanced (92%) or metastatic disease (19%). Vascular invasion was identified in 29% of specimens, while perineural invasion was found in 38% of cases. Colon cancer patients undergoing emergency radical surgery display independent risk factors for the postoperative and the overall oncologic outcomes, such as comedo-necrosis, high lymph node involvement, locally advanced or metastatic disease, and perineural and vascular invasion.
